OK. Your first test using Advanced > Write creates a temporary ISO using "mkisofs -r -J -f", then burns it with "cdrecord -multi -data". This combination should be most compatible with devices like your player.

Your second test uses "mkisofs -r -D -isolevel 4 -f" and "cdrecord -dao -data". This one is designed to work in Linux-compatible situations.

So I'm not surprised that your first test worked and the second one failed.

I tried to use PeasyDisc in Precise Puppy to burn a backup of my favorite DVDs to a rewritable Blu-Ray disc. Here's what happened: Nothing.

If it makes you feel any better, Pburn does the same thing, only it fakes burning for half the Blu-Ray disk before stopping and giving essentially the same error message as PeasyDisc did. PeasyDisc tells me right away that it won't work.

I assumed that I didn't need to blank the BD-RE disc before telling PeasyDisc to burn the folder containing 5 x 4.4 GB iso files onto it. ROX says the total size of the folder I was trying to burn is 22 GB.

In the terminal window, you can see the reference to genisoimage. The optical burning tools in Precise cannot handle files greater than 4 GB. You need to use a Puppy that has the appropriate tools. See the discussion about Blu-ray on Page 3.

It may be possible to upgrade Precise to handle large files. Go into /usr/bin and locate three files - genisoimage, mkisofs and growisofs. Some of them may be symlinks. Then go into Upup Raring and find the matching files. Copy them from Raring to Precise.

In Precise, mkisofs is a symlink to genisoimage (from the old cdrkit package I believe).

My cdrtools-3 package for Precise contains a mkisofs which is a real file. You could try installing that. I compiled it as a dependency for upgrading to latest pBurn and you can download it from here:-

The growisofs file is part of a different package, dvd+rwtools, which I thought was already in Precise. I did compile it from source for Wheezy because it seemed to be missing or not working properly in 3.5.2.7 and I believe it is now included in 3.5.2.8. Did you compile those that you posted, rcrsn51?_________________Oscar in England

Correct.

Is PeasyDisc trying to execute genisoimage directly or mkisofs?

PeasyDisc only ever calls mkisofs. In Precise, that gets you genisoimage. However, in Flash's situation, it is growisofs that is calling genisoimage, not PeasyDisc.

It is. But some versions of growisofs are built to use cdrkit instead of cdrtools. These ones cannot process large files.

Even if you compile dvd+rwtools from source against cdrtools, it will still not work properly with Blu-ray. There are patches in the Debian repo that fix an assortment of problems. My builds of growisofs contain them.Last edited by rcrsn51 on Sat 01 Apr 2017, 20:49; edited 1 time in total

Since I run Puppy from a multisession DVD, I'm not married to a particular version of Puppy. It's no trouble at all for me to switch to a different version. I could download the latest version of Slacko, if you think that's the version of Puppy most likely to have the tools to do what I want, burn it to a DVD-RW and try it out. If it works, then I'd know that Slacko has all the right stuff. I'd be willing then to try to upgrade Precise Puppy just to see if it could be done.

So which version of Puppy is most likely to be able to burn >4GB files, do you think? And, assuming I find one that works, what I do then, to upgrade Precise Puppy?

FWIW, I'm pretty sure I tried to burn a 24 GB file to a BD-RE disk with Pburn in Fatdog64-602 and it didn't work, so Fatdog may also have the old toolkit.

If you are currently using Precise, go up three posts and get Oscar's cdrtools package. Then go to page 3 and get my growisofs_slacko56-7.1.pet

Okay, that's what I did and the 22 GB folder is burning as I type this. Looks like it will take an hour an a half to finish (The disk is a BD-RE which can only burn at 2x). Assuming it finishes the whole enchilada, I'll do the 24 GB file next. Maybe I'll try that one in Pburn to see if your growisofs package and Oscar's cdrtools package fixed that too.

I've never seen Oscar's download site before. That's a lot of good stuff.
